THE INKJET PRINTER HISTORY

When did the InkJet printer first come into existence?

The Inkjet printer produces a digital image by spraying droplets on
demand onto paper, and are the most commonly used printer today, largely due to
their low entry cost which has found favour with the home and small office
user.

The first recording device, using electrostatic forces, was invented by William Thomson, later Lord Kelvin, in 1858. This was the Siphon recorder. The apparatus was used for automatic recordings of telegraph messages and was patented in 1867

The first practical continuous Inkjet printing device was patented by Elmqvist of Siemensin 1951, with the rapid development of inkjet technology starting off around the late fifties. But not much happened until
1977 when Siemens introduced the PT-80 serial character printer. This printer
ejected ink droplets on as it was needed to print, as opposed to continuous
inkjet technology that IBM had developed earlier in the 1970’s., which was far
more complex , and far more expensive.

Also about then Canon introduced bubble jet printer technology, a drop
on demand inkjet printing method where ink drops were ejected from the nozzle by the fast
growth of an ink vapour bubble on the top surface of a small heater. HP
did likewise and coined the name ‘thermal inkjet’.

the replacement of the piezoelectric by a thermal transducer, the main bottleneck

concerning miniaturization was resolved. The thermal transducer became a

simple, small, and cheap resistor

Today, the technology used for inkjet & bubblejet
printers is the serial printing process, where the printer uses print heads
with nozzles arranged in vertical columns – a process which is the same as is
used in dot matrix printers.

The dot matrix printers ( both serial & line dot matrix printers
are the most popular today owing to the fact that they are the least cost per
page for print usage when compared to other inkjet printers.

So don’t just sit there - go and use your inkjet printer to print this
out.
